"A new poll conducted by Military Times and Syracuse University has found that nearly half of all active duty American troops believe the next major war is just around the corner.

The poll results show about 46% of respondents think the U.S. will be drawn into a new war at some point in the next year, which is a significant 5% leap above the same category in the Military Times poll taken last year.

Analysts who looked at the numbers believe military personnel fear global instability and the heightened rhetoric of the Trump administration especially related to world powers like Russia and China."

How prevalent were firearms during the Renaissance?

At what point did firearms replace pole arms as the primary weapon for infantry?

At what point did bows and crossbows become uncommon on the battlefield?

At what point did plate armor begin to disappear?

How did Renaissance tactics differ from late medieval tactics?

I keep getting conflicting answers to these questions everywhere else. Also, general Renaissance thread. Post your favorite battles, commanders, weapons, etc. from that period.

I'm trying to avoid going on an autistic rant about how Spengler is completely right, and this ancient-medieval-modern trinity of history is wrong and should be abandoned so that people can focus on the rise of high cultures and fall of civilizations. Just consider this: the renaissance was originally a small circle of Italian intellectuals going "we wuz romanz an' shiieet", whostarted aping Greek and Roman art, or at least what they thought it was. Just consider that they fetishized white marble, while those white marble statues were originally brightly coloured and looked like an eyesore. Then during the enlightenment the bourgeoisie of Europe wanted to mock and ridicule the nobility and the priesthood. For this purpose they invented the myth of the "dark ages" after the fall of Rome that was a period of decline caused by what later became the Catholic church and the European nobility. For this to work they looked at that small circle of Italian intellectuals and pretended that it was some kind of a great rediscovery of lost knowledge and without them the average European would be living like a German tribesman in the 6th century. And that's why this small artistic movement became a historical period.

More than the "small circle of italian intellectuals going we-wuzing", the Renaissance was the context which led to it and made it possible: i.e. first the stability of the italian city-states, second their wealth, third the very important volume of trade (and ensuing cultural exchange) between the city-states and the city-states and the rest of Europe; and fourth, the desire of the cultured élites (most famous among them the Medici of Florence) governing those city-states to foster cultural growth, due to a breadth of reasons of which we-wuzing the romans (both to share some of their prestige and out of sincere fascination) is only a part.

As for the antiquity/middle ages/modern age division, I think that the pendulum has swung too far in denying it: the differences between, for instance, antiquity and middle ages culture, society and, more evidently, power structures and hierarchies, is way more pronounced and clear-cut than among antiquity: the passage between late roman empire and early middle ages is evident and more marked than the one between late roman republic and early empire, for instance (famously, most roman intellectuals at first didn't even realize the change had happened, and hailed Augustus as the saviour of the Republic against a return to a one-man tyranny).

Lastly, and related to my last point, I don't think calling the dark age a "myth" is entirely justified. While I do agree that some people think of it as a "stagnant" age with no advancements, which is patently untrue, it is undeniable that it was a period of decline: standards of living falling, loss of technical and technological knowledge (mostly in "advanced" fields such as medicine and architecture), and loss of cultural wealth (due to the absence of the stable, rich context necessary to its development, and to the radical cultural shifts of which I was talking earlier).

Focusing more on the cultural aspect, of course there were "lights in the dark": but the quantity (and, some would say, quality) of authors and their works was way lower than that of both the period that came before and the period that came after (which saw starting from the 1250s sPost too long.

I think thirsty men reject any marketing campaign anyhow. People will cry sharp knees at super models but then happily fawn over hamplanets irl.

This, is basically what I was saying. Also this:

>There is a level of hotness that appeals and it's not always super hot.

In the sense that actual men will always want the hottest woman possible, but cucks and betas have such poor confidence that they are intimidated by attractive women so average sixes work better with them.

I'll further support it by pointing out that you can go on Youtube and easily find more attractive thots blogging about their military life.

>Money is already worthless. They can print as much as they want and decide it's value on a whim.

Yet the thing that would collapse the monetary house of cards are things like nobody using it or everyone cashing in for gold or alternative currency. This is the biggest reason governments are shit scared of bitcoin and put gigantic punishments on moonshining- there is no way to tax a transaction made over the fence. Additionally, they cannot decide how much it's worth on a whim when they can't even keep track of a single muslim extremist, let alone force other nations producers to accept a dictate that their product is worth this much paper. Were china to stop accepting american paper, and suddenly call it in for its foreign debts, war would ensue by america terrified of actually paying it.

Any rational person would presume the "escape route" for a military aircraft would involve the airplane flying somewhere else.

He though that the Soviets were like the French of the Tzarist regime, where they would surrender to the Germans after a few loses. The truth was that the Soviets would rather have there country be one large graveyard than be occupied.

How Jewish the Bolsheviks were was debatable, however what isn’t debatable is the fact that what the Germans wanted to do to the Russians was a million time worse then anything the Soviets could’ve done. Hitler didn’t see Slavs as white, infant he saw them as less than Jews. Hitler wanted to genocide all Slavs, which includes Russians, and replace them with German settlers. To the Russians anything was better than that. Which is why they agreed to Stalin’s policy of hoping he had more men the the enemy had bullits, because they new what the Germans would do was worse. In this since Hitler caused his own downfall. If he saw the Russians, and East Slavs as a whole as an Aryan people, WW2 would’ve probably been won by Germany. But he didn’t, and the rest is history.

>The new ‘draft’ PON seeks both an NGSW-R, the planned replacement for the M4/M4A1 carbine, and a NGSW-AR (Automatic Rifle) to replace the M249 Squad Automatic Weapon (SAW).

>The new PON also differs in that it is seeking two weapon systems that can fire “Government provided 6.8 millimeter projectiles” with vendors expected to develop a cartridge, which fits defined lethality requirements, using the government projectile. The two weapon platforms must also have magazine interchangeability – if the NGSW-AR feeds from magazines.

>The PON leaves the ammunition carriage system of the NGSW-AR open while stipulating magazines for the NGSW-R. Both weapons, however, must use the same round.

>While we can’t comment on the ammunition requirement fully as this is set at Distribution F, and not freely available, the draft PON appears to dictate the weapon’s ammunition by stipulating a specific projectile. The PON states that the government’s new ‘6.8MM GENERAL PURPOSE (GP)’ projectile, designated the XM1186, must be used to develop a round that will provide “all-purpose solutions for combat, limited training, and basic qualification.” In a change from the previous PON the Government also states that submitting vendors may work with the Government-owned Contractor-operated Lake City Army Ammunition Plant may be used as a subcontractor to work on ammunition development.

Sounds like a GPC is back on the menu.

Of course, that's the oldest way of doing it. Simply increase case size for both moar powder, also more actual area of pressure to build up into. Its why a 30-06 held to lower pressures by SAAMI in the US has same or even slightly better ballistics than a 308 at higher pressure. See the 45-70 Gubmit's bigger brothers from the blackpowder era, such as the 45-90 and 45-120, even at the same pressure there is greatly increased performance at the same pressure due to more area inside the case because of that larger case size.

The little secret of increasing power in a cartridge is this (don't tell anyone) the advantages of case design efficiency aren't the great or impressive. They do change dynamics, but the idea you can change the cartridge enough to perform miracles, much less major changes, is laughable. In the end its much more simple changes that end up making up performance like sheer case size capacity more than anything else.


Short and fatter cases may have some small advantage in slow burning powder, but keep in mind that old fashioned straighter cartridges were superior with fast burning powder and lighter loads, therefore the assertion that "short and fat is better" is not quite true, it simply has a small advantage with certain powders and certain bullets. Old Mauser family cartridges like the 30-06, 8mm, 6.5 Swede, and long magnums like the 375 H&H, as well as straighter blackpowder like 45-70 Gumit, are all well known for their various qualities in full power rounds, but are also exceptionally well performing at lower loads. Reduce the pressure, choose faster burning powders, suddenly the edge goes back from these new super shorts back to classical long. 300 Whisper isn't a super short stubby, now is it, considering they want it for suppression and subsonic? 30-06 is legendary in cast rifle circles, 375 H&H is well known for reduced jack bullet loads for deer. 300 Win Mag, much less more radical short stubbies, are not good at either cast or reduced loads because its dePost too long.

Also consider that efficiency actually results from size issues yet again. To achieve the same performance with the same bullet, a smaller cartridge that obtain that same performance will have the edge in efficiency. Larger case capacities lead to greater potential, but also more waste. Noslers new super medium bores are highly inefficient. 308 is more efficient than 30-06 because it is smaller, more efficient to load up a 308 to higher pressure than to load down the larger 30-06. A Japanese doctor I watch on the Youtube went on about this familiar issue, with reloading components 2-3x that of the burgerlander, he would have long term cost savings going to 308 as he correctly calculated. If we really break down some of the loads using 243 and 243 WSSM, is the efficiency in the shoulder, or is the efficiency in the fact that the shorter case actually might end up with total less case capacity when the long bullets are pushed into the shorter case into the powder area? Another note of fat vs slims, 300 H&H is less powerful all the way up to 220 grain bullets against the 300 Win Mag, because 300 Win Mag's shortness comes at a cost with super heavy bullets as they interfere with the case space as they are deeply seated in the powder area. Is the efficincy of the stub more to do with the big bullet making less space in the case and increasing efficinecy, or just because of the shoulder?

I should have added those were the minimum loading's for .243 wssm while the .243 winchester loads were at their maximum. Source is Lyman's reloading manual 49th edition.



Well WSSM cartridges are meant to be high pressure, high performance cartridges and perform best when loaded hot; ~61k psi. They're not meant to be loaded with reduced power loads. Unfortunately the shorter actions restrict bullet length which is a bit of a shame as they fall into this odd 2.35-2.5" OAL category, too long for AR-15's (although there are some uppers chambered for the three of them) and not long enough to fall into the 2.8" range. As for capacity you won't be getting much but this cartridge wasn't designed to be used in a semi-auto. It was made as a bolt action cartridge meant for hunting or in long range shooting. I agree though, they are not practical outside of that setting. I couldn't tell you why they are more efficient at comparable bullet weights but they definitely are limited in what they can do compared to larger cartridges that have greater flexibility. I only brought the WSSM up to show how case dimensions can affect velocity.

To get back on topic, telescopic cases seem to combine the best of both worlds. 70-100k psi pressures in a straightwall-esque cartridge. If you want more power just make the case 0.5" longer. I'm not sure how well they would do with reduced loads however. I would suspect obturation would be an issue with plastic cases as the plastic would simply undergo elastic deformation under lower pressures.

Thank you, kind sir for your detailed explaination. Now i can clearly see that you truly are a man of culture.

Addressed to >>618182 >>618183

but your >>618241 information is plentiful as well.
